The ASLA Medal is the highest honor the American Society of Landscape Architects (ASLA) may bestow upon a landscape architect whose lifetime achievements and contributions to the profession have had a unique and lasting impact on the welfare of the public and the environment.

Man is a professor and head of the Department of Landscape Architecture at Mississippi State University. He has taught and graduated 950 baccalaureates, 115 master's candidates, and 225 recipients in landscape contracting and management. Man has also had a direct impact on the profession as a past president of ASLA, the British Columbia Society of Landscape Architects, the Manitoba Association of Landscape Architects, the ASLA Mississippi Chapter, the Council of Educators in Landscape Architecture (CELA, on two occasions), the CELA Foundation, and the Landscape Architecture Foundation.

Perhaps his greatest contribution to the profession and society is the accomplishment of his former students: one is now the Deputy Minister of Education in British Columbia; two are currently Deans of Design Colleges; four are department heads of landscape architectural programs; and over thirty are full time faculty in landscape architecture departments. In terms of service to the profession, one former student has served as president of the ASLA, one currently serves as president of the Canadian Society of Landscape Architects, and three currently serve as trustees of the ASLA. On an international level, former students are resident practitioners in 23 countries, one of whom is currently the president of the Nigerian Association of Landscape Architects.
